<p>The invention relates to a method for determining the position of an elongated piece, particularly its end point (p2). In applying the method, two points (p1, p2) are defined in an elongated piece, the distance (L) therebetween being known. For applying the method, at least on acceleration sensor (2) is placed in connection with the elongated piece (1) for measuring acceleration forces active on the elongated piece in an elected vertical measuring plane passing through the two points (p1, p2). The acceleration sensor (2) is connected with a computing unit for computing the horizontal and/or vertical projection (Pι, Pk) between the said two points. The invention relates also to the use of an acceleration sensor in measuring the position of an elongated piece. The invention is intended for use in measuring the position of beam structures in connection with working machines, such as excavators, access platforms or the like.</p> |
